Recently learned, the EU is accelerating the development of the Digital Euro to maintain financial sovereignty and respond to the threats posed by dollar stablecoins. At the same time, the ECB is actively evaluating the use of public chain technology (such as Ethereum or Solana) to introduce a more open, transparent, and scalable payment architecture. This represents a departure from the traditional central bank digital currency framework, adopting a globally innovative financial design. If successfully implemented, it would not only enhance the competitiveness of the Euro in international payment networks but also open a new chapter for cross-border digital payments and financial integration.
